Aww, congratulations on your BFP selepas 8 tahun TTC, that's so amazing! A few hari perbezaan antara dates dan scan measurement tu actually very normal, especially kalau implantation lambat atau cycle irregular; most doctors akan go by scan dating daripada LMP alone. Tapi sebab you ada sejarah janin tak membesar before, I think it's really important you have a proper heart-to-heart with your doctor, tanya dia specifically about this measurement and what she's looking for at your next scan, sebab dia akan monitor you closely and dapat advise based on your full history. One of my mum friends also had similar worries lepas previous loss, and her consultant gave her extra scans just untuk peace of mind, which helped her SO much. Sending you all the doa, ini adalah your time, mama.
